Answer:
D
Step-by-step explanation:
Answer:
supplementary , or linear pair 158
Step-by-step explanation:
The two angles are supplementary angles since they form a straight line
b+22 = 180
b = 180-22
b = 158
You have to divide 112 by 2 which is 56 then multiply it by three and you get 168
Answer:
a_n = 28-2n
Step-by-step explanation:
Given sequence is:
26,24,22,20
We can see that the difference between consecutive terms is same so the sequence is an arithmetic sequence
The standard formula for arithmetic sequence is:

Here,
a_n is the nth term
a_1 is the first term
and d is the common difference
So,
d = 24-26
= -2
a_1 = 26
Putting the values of d and a_1

Hence, the recursive formula for given sequence is: a_n = 28-2n ..
